DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Is it necessary to erase permanent DTC? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Is the inspection result normal? YES >> GO TO 5.
NO >> Proceed to EC-212, "Diagnosis Procedure".
3.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
4.PERFORM DTC CONFIRMATION PROCEDURE
NOTE: Cool the vehicle in an environment of ambient air temperature between −10°C (14°F) and 35°C (95°F).
CAUTION: Never turn ignition switch ON during this procedure.
NOTE: The vehicle must be cooled with the food open.
CAUTION: Never turn ignition switch OFF during idling.
Is 1st trip DTC detected? YES >> Proceed to EC-212, "Diagnosis Procedure".
NO >> INSPECTION END
5.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Diagnosis Procedure
1.CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Check ECT sensor. Refer to EC-212, "Component Inspection".
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace ECT sensor. Refer to CO-23, "Exploded View".
2.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace engine coolant temperature sensor. Refer to CO-23, "Exploded View".
